Who Was the First Scientist?

We live in a scientific age. Millions of young citizen study science, thousands of universities teach it, and hundreds of publications narrate it. We even have a cable channel devoted exclusively to its wonders. We are immersed in technology rooted in its discoveries. But what is science, and who was its first practitioner?

Science is the study of the corporeal world, but it is not just a topic, a subject, a field of interest. It is a discipline--a system of inquiry that adheres to a definite methodology--the scientific method. In its basic form, the scientific method consists of seven steps:

Anthology

1) observation;

2) statement of a qoute or question;

3) formulation of a hypothesis, or a possible riposte to the qoute or question;

4) testing of the hypothesis with an experiment;

5) determination of the experiment's results;

6) interpretation of the data and formulation of a conclusion;

7) publication of the findings.

One can study phenomena without adhering to the scientific method, of course. The result, however, is not science. It is pseudoscience or junk science.

Throughout history, many citizen in many parts of the world have studied nature without using the scientific method. Some of the earliest citizen to do so were the ancient Greeks. Scholars such as Aristotle made many observations about natural phenomena, but they did not test their ideas with experiments. Instead they relied on logic to preserve their findings. As a result, they often arrived at erroneous conclusions. Centuries later the errors of the Greeks were exposed by scholars using the scientific method.

Perhaps the most paramount debunking of Greek beliefs occurred in 1589 when Galileo Galilei challenged Aristotle's notions about falling bodies. Aristotle had asserted that heavy bodies fall at a faster rate than light bodies do. His contention was logical but unproven. Galileo decided to test Aristotle's hypothesis, legend says, by dropping cannon balls of dissimilar weights from a balcony of the Leaning Tower of Pisa. He released the balls simultaneously and found that neither ball raced ahead of the other. Rather, they sped earthward together and hit the ground at the same time. Galileo also conducted experiments in which he rolled balls of dissimilar weights down inclines in an exertion to gawk the truth about falling bodies. For these and other experiments, Galileo is thought about by many to be the first scientist.

Galileo was not the first person to escort experiments or to succeed the scientific method, however. European scholars had been conducting experiments for three hundred years, ever since a British-born Franciscan monk named Roger Bacon advocated experimentation in the thirteenth century. One of Bacon's books, Perspectiva (Optics) challenges ancient Greek ideas about foresight and includes any experiments with light that consist of all seven steps of the scientific method.

Bacon's Perspectiva is not an original work, however. It is a overview of a much longer work entitled De aspectibus (The Optics). Perspectiva follows the assosication of De aspectibus and repeats its experiments step by step, sometimes even word for word. But De aspectibus is not an original work, either. It is the translation of a book written in Arabic entitled Kitāb al-Manāzir (Book of Optics). Written around 1021, Kitāb al-Manāzir predates Roger Bacon's overview of it by 250 years. The author of this groundbreaking book was a Muslim scholar named Abū 'Alī al-Hasan ibn al-Hasan ibn al-Haytham.

Born in Basra (located in what is now Iraq) in 965, Ibn al-Haytham --known in the West as Alhazen or Alhacen--wrote more than 200 books and treatises on a wide range of subjects. He was the first person to apply algebra to geometry, founding the field mathematics known as analytic geometry.

Ibn al-Haytham's use of experimentation was an outgrowth of his skeptical nature and his Muslim faith. He believed that human beings are flawed and only God is perfect. To gawk the truth about nature, he reasoned, one had to allow the universe to speak for itself. "The seeker after truth is not one who studies the writings of the ancients and, following his natural disposition, puts his trust in them," Ibn al-Haytham wrote in Doubts regarding Ptolemy, "but rather the one who suspects his faith in them and questions what he gathers from them, the one who submits to discussion and demonstration."

To test his hypothesis that "lights and colors do not blend in the air," for example, Ibn al-Haytham devised the world's first camera obscura, observed what happened when light rays intersected at its aperture, and recorded the results. This is just one of dozens of "true demonstrations," or experiments, contained in Kitāb al-Manāzir.

By insisting on the use of verifiable experiments to test hypotheses, Ibn al-Haytham established a new system of inquiry--the scientific method--and earned a place in history as the first scientist.
